When you arrive at abunai, you will get a map.
I believe its in the same place where karoake normally is, and if thats the case you probably can't miss it, if you walk through the entrance the first room left is it. Well, that was last year.

Like the CFS, the Karaoke competition has also reached full capacity. But for the karaoke competition we have decided to extend the maximum amount of participants from 20 to 25. Unfortunately, these last 5 spots have also been filled. So it is not possible anymore to sign up for the Karaoke competition.

There is still the regular karaoke though, so if you want to sing we invite you to come to the free karaoke bar in the 'Diezehal' and join in!
